70% to passTo operate a portable foam fire extinguisher, you should _______________.
Aopen the hand wheel
Bpuncture the CO2 cartridge
Cpull the pin and squeeze the trigger
Dturn it upside down and bump the deck
AI Explanation
The correct answer is C) pull the pin and squeeze the trigger. To operate a portable foam fire extinguisher, you should pull the pin and squeeze the trigger. This releases the pressurized foam agent stored in the extinguisher, allowing you to direct it at the base of the fire. Turning the extinguisher upside down and bumping the deck (option D) is incorrect, as this would not properly discharge the foam. Opening the hand wheel (option A) or puncturing the CO2 cartridge (option B) are also incorrect, as these actions are not the proper way to operate a foam fire extinguisher.
